Also, because the welding strength can't reach the original new car standard, the whole car will have major safety hazards. Because the body manufacturing is a whole, although it is welded, it will destroy other existing solder joints. Therefore, after re-welding, the solder joint can not reach the strength of the original solder joint, which affects the safety of the whole vehicle.

The function of the right fender is to prevent the mud or sand rolled up by the wheels from splashing to the bottom of the carriage during driving and protect the bottom of the carriage.

Extended data

1, fender

Fender is the outer panel of the car body covering the wheels, which is named after the shape and position of this part on the old car body like bird wings. According to the installation position, it is divided into front fender and rear fender. The front fender is installed at the front wheel, which must ensure the maximum limit space when the front wheel rotates and jumps. Therefore, the designer will use the "wheel jump diagram" to verify whether the design size of the fender is appropriate according to the selected tire model size.

2. Type

There is no wheel rubbing problem on the rear fender, but due to aerodynamic considerations, the rear fender is slightly arched and protrudes outward. The fenders of some cars have been integrated with the body in one go. However, there are also fenders of cars that are independent, especially the front fender, because there are many collision opportunities of the front fender, and it is easy to replace the whole piece by independent assembly.

3. Structure

The fender is arranged above the wheels of the vehicle, and is used as the outer panel of the vehicle side, and is molded from resin. The fender is integrally formed by an outer panel portion exposed on the side of the vehicle and a reinforcement portion extending along an edge portion of the outer panel portion provided on the inner surface of an adjacent component adjacent to the outer panel portion, while an assembly portion for assembling the adjacent component is formed between the edge portion of the outer panel portion and the reinforcement portion.
